Power Line Filter Modules

The NBH-20-331-D is a power line filter module designed to suppress common-mode and differential-mode interference in a range of applications. This filter module is designed to filter out the EMI caused by the current from power supplies, ensuring they are functioning properly and meet EMC requirements. It is also designed to provide effective filtering even with large dynamically changing loads.

Application Field

The NBH-20-331-D power line filter module is designed for industrial, transportation, and medical applications, as well as many other applications where power line filtering is required. It is a very versatile power line filters module for a variety of applications, providing effective filtering even with large dynamically changing loads.

Working Principle

The NBH-20-331-D power line filter module works by using three different techniques for filtering: common-mode choking, differential-mode capacitors, and RFI and EMI absorption filters. The first two, common-mode choking and differential-mode capacitors, are used to filter out the common-mode and differential-mode interference from the current, while the RFI and EMI absorption filters help reduce the amount of electromagnetic radiation from the power supplies, helping to ensure that the power supplies meet EMC requirements.

The common-mode choking is used to reduce high-frequency interference caused by current flowing through the power supply. The differential-mode capacitors help to reduce the amount of voltage drop across the power line, while the RFI and EMI absorption filters help to reduce any radiation that escapes from the power supplies.

Conclusion

The NBH-20-331-D power line filter module is a versatile and effective solution for a variety of power line filtering applications. It is designed to provide effective filtering even with large dynamically changing loads, and its three-tiered filtering system helps ensure that power supplies are operating correctly and meeting EMC requirements. As such, it is an ideal choice for industrial, transportation, and medical applications, as well as many other applications where power line filtering is required.
